ultimately, this discussion of "real" music is subjective.
Here's how i do it. Don't matter what genre it is...toes tap and head rocks, its good. You can catch me blasting slipknot to crystal castles to die antword to sum 41 to limp bizkit to a tribe called quest to the roots to korn to erykah badu to eifle 65 to tupac to collective soul to michaelangelo batio to the cool kids to nas to blink 182 to sugar ray to johnny cash to lil kim to rage against the machine to sublime to kanye west to led zepplin whatever.
Music is music, and support the local!! (y'all need to open your minds up a bit)
